1. execute SimpleBPMNProcessTest in jbpm-bpmn2 module
2. search for testSubProcess
  
Actual results:
RUNNING: testSubProcess
x = null
x = Hello
Goodbye World

"toString of ProcessVariableChangedEvent from beforeVariableChanged()"
"toString of ProcessVariableChangedEvent from afterVariableChanged()"
x = Hello

Events are generated properly but they are not printed out by default since they use logger and its debug level, which is disable. Can be enabled in src/test/resources/log4j.xml.
When enabled exected events are printed out.

Tomáš, is this still valid? If not, please close.
Comment 3 Tomas Schlosser 2012-03-21 07:28:22 UTC 
It seems that the problem was somewhere else. We check changed variables by variable ID, but the ID of variable inside the subprocess is not '<variable_name>', but rather '<subprocess_node_id>:<variable_name>'.

Could you please document that? So the users know what to expect.
